我在一个文件中流式传输推文tweet.txt并使用另一个 python 脚本,我正在阅读推文并将它们发送到 Watson。有时,会产生错误:

回溯(最后一次调用):文件“readingTweets.py”,第 44 行,语言='en' 文件“/usr/local/lib/python2.7/dist-packages/watson_developer_cloud/natural_language_understanding_v1.py”,第 173 行,在分析方法='POST',url=url,params=params,json=data,accept_json=True)文件“/usr/local/lib/python2.7/dist-packages/watson_developer_cloud/watson_service.py”,行385, 在请求 info=error_info, httpResponse=response) watson_developer_cloud.watson_service.WatsonApiException: Error: invalid request: content is empty, Code: 400 , X-dp-watson-tran-id: gateway02-582988317 , X-global-transaction -id: ffea405d5adda40d22bfb21d

我的代码示例是:

while 1:
    where = file.tell()
    line = file.readline()
    if not line:
        time.sleep(1)
        file.seek(where)
    else:
        if (line):
            print "-----------------------------"
            print "the line is: "
            print line
            print "-----------------------------"
            response = natural_language_understanding.analyze(
                text=line,
                features=Features(
                    entities=EntitiesOptions(
                        emotion=True,
                        sentiment=True,
                        limit=2),
                    keywords=KeywordsOptions(
                        emotion=True,
                        sentiment=True,
                        limit=2)),
                language='en'
                )
            print(json.dumps(response, indent=2))

它是什么Error: invalid request: content is empty no content或无效字符。您建议有类似\nused 的字符,而您只检查了空字符。
